Hi all. My brother has a horrible cold. Before he goes to the doc for antibiotics, I wanted to know if anyone has used any of the immune system promoting herbs to fight off a bacterial or viral infection? Echinacea and Goldenseal are the 2 major ones - anyone get results from these? What about mega high doses of vit C (6g or more per day)? I was hoping just low carbing for a few days without dairy, grains, legumes, etc would do the trick but his situation hasn't improved. Thanks, Justin Hasselman
